Porous tin disulfide nanosheets with room temperature ferromagnetic nature

Abstract

Two-dimensional nanomaterials usually have abnormal physical properties due to surface effects and large edge states. In this communication, it is demonstrated that porous hexagonal disulfide nanosheets exhibit clear room temperature ferromagnetism, where the observed ferromagnetism can be tuned by changing the porosity of the nanosheets. The disordered grain boundary, or defects in the nanosheets, is considered to be responsible for the long-range magnetic order. This finding suggests a route to facilitate the design of nanoelectronic devices.
